Troubles hooting Guide for ICP Optical
Emissi on Spectrometers
Introduction
In this report, we will examine the causes and corrections for five common problems that can
arise for ICP optical spectrometers as follows:
• Poor precision
• Carryover
• Drift
• Degraded detection limits
• Inaccuracy
The order of these is important in that each problem can only be addressed once all
characteristics above it have been resolved. For example, inaccuracy issues can only be
addressed when the instrument is demonstrating acceptable short-term precision and
carryover, negligible drift and adequate limits of detection. Precision is the first peel of the
onion and must always be optimized first.
To facilitate troubleshooting, you should have periodically generated data (control charts) that
gauge an appropriate selection of criteria for each spectrometer. This will make it easier to find
the cause when something goes wrong and these will be detailed below.
